Paper Abstract

An optical fiber sensor for the simultaneous measurement of hydrostatic pressure and temperature in soil embankments is presented. The sensor exploits a dual chambers transduction mechanism and is based on the optical measurement of the differential strain induced in the fiber by temperature and pressure in the two chambers. A prototype has been built and interrogated by means of optical coherent frequency domain reflectometry and the results of a preliminary experimental characterization are presented and discussed. Temperature and pressure sensitivities are approximately -7.1 GHz/°C and -4.4 GHz/kPa, respectively.
